'To all whom it may concern:

Be it known that I, MARK J. QUIMBY, a citizen of the United States, residing at Bristol, in the county of Addison and State of Vermont, have invented certain new and useful Improvements in Hydraulic Power Apparatus, of which the following is a specioation, reference being had to the accompanying drawings.

This invention relates to improvements in hydraulic power apparatus and has for its object to improve and simplify the construction of apparatus of this character and to provide means for storing water under various pressures.

Another object of my invention is to provide means whereby the use of cylinders and reciprocating pistons for obtaining the desired pressure is entirely eliminated.

A further object is to provide a tank for storing water under pressure, said tank being divided into four chambers, and means for supplying water under pressure to each of said chambers, said means also varying the pressure in each chamber.

A still further object is to provide a plurality of pressure chambers surrounded by a body of water which is adapted to reduce the heat in the chambers generated by the pressure fluid, and a rotary valve connected by means of an inlet and exhaust pipe to one of the chambers to supply pressure iiuid thereto.

With these and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a vertical section through the outer casing and the water storage tank or reservoir, the valve being shown in elevation; Fig. 2 is a section taken on the line 2 2 of Fig. 1; Fig. 3 is a section taken on the line 3 3 of Fig. 1; Fig. 4 is a section taken on the line 4 4 of Fig. 2; Fig. 5 is an enlarged detail section of the rotary valve; and Fig. 6 is a sect-ion taken on the line 6 6 of Fig. 5.

Referring more particularly to the drawings 5 indicates the outer casing or housing in which the tank or reservoir 6 is contained. The walls of the tank 6 are spaced from the walls of the casing 5 and in this space water is contained. The top and bottom walls of the tank 6 are connected by means of a plurality of tubes 7 thereby allowing the water to rise in said tubes between the walls of the tank. This body of water in which the tank 6 is disposed is adapted to lower the internal temperature of the tank, said water gradually increasing in temperature thus maintaining a heated surrounding body for the tank.

As will be noted from reference to Fig. 2 the tank 6 is divided into a plurality of chambers or compartments 8 by means of the partitions 9 which are arranged in the tank and secured to the walls thereof in any desired manner. A stand pipe 10 communicates with one of the chambers 8 and is adapted to supply the water thereto from whence it is conducted to the remaining chambers as will more fully hereinafter appear. In the chamber 8 with which the stand pipe 1() communicates a valve 11 is arranged. This valve consists of the usual valve casing with which a vertical pipe 12 is connected. The entrance point of this pipe to the valve casing is partially closed by means of the angularly disposed plate 13 which may be integrally formed with the valve casing and extends inwardly and downwardly below the pipe 12. A valve plate 141 is pivoted in the valve casing and has a flange or lip 15 formed upon one end which is adapted at times to entirely close communication between the valve and the pipe 12 as clearly shown in Fig. 4. This valve plate is pivoted adjacent to the lip 15 and is normally disposed in the position indicated by the dotted lines, said valve plate moving to such position by gravity upon decrease of water pressure in the chamber 8. A pipe 16 also extends from the valve 11 through one of the partitions 9 into the adjacent chamber 8. The pipe 12 is extended into another of said chambers 8a and a pipe 17 communicates with the pipe 12 and opens into the remaining chamber 8b. A check valve 18 is arranged in each of the pipes 12, 16 and 17 and prevents back pressure ot' the water from the chambers in said pipes. A similar check valve 19 also is arranged at the point of communication with the pipe 17 ot the pipe 12 and is adapted to close the pipe 17 under pressure of the water in the pipe 12. A check valve 20 is also arranged in the stand pipe 1Q and prevents back pressure of the water in said pipe from the chamber 8 in which the valve- 11 is located.

The supply of pressure fluid to the apparatus is controlled by means of the rotary valve illustrated in Figs. 5 and 6. This valve is arranged upon an inlet and exhaust pipe 21 communicating` with the chamber 8 in which the valve 11 is arranged and extending through the outer casing 5. The rotary valve comprises a casing 22 which is threaded or otherwise secured upon the pipe 21. Upon this casing a head plate 23 is secured in Which a valve seat is formed. The rotary valve plate 24 is disposed upon said seat and is secured upon an arbor 25 the end ot' which extends through the head plate 23 and has a nut 26 threaded thereon to secure the same in the valve casing. Upon the other end of the arbor 25 a band pulley 27 is secured over which the driving belt 28 passes. An inlet and outlet pipe 28 and 29 respectively are secured in the head plate 23 and are adapted to register with an opening 30 in the valve plate 24 when the same is rotated. rThe pressure fluid may be either steam or gas and when the latter is used a spark plug 31 is arranged in the valve to explode the gases and discharge the same into the tank chamber 8.

In the operation of the apparatus, when the opening in the rotary valve plate registers with the outlet pipe 29 so as to exhaust the steam or gas from the chamber 8, water enters said chamber Jfrom the stand pipe 10, the check valve 2O preventing back pressure of the water in said pipe when the rotary valve is closed. As the valve plate is rotated to aline the opening therein with the intake pipe 28, steam is admitted to the chamber 8 through the pipe 21 and the water therein thus placed under pressure and forced through the valve 11. This pressure otl the water in the valve raises the valve plate 14 to the position shown in full lines in F ig. 4 thus closing communication between the chamber 8 and the pipe 12. Tater is discharged through the pipe 16 into another of the chambers 8 as long as the pressure of Water in the valve is sufficient substantially the same height, the pressure in the chamber 8 will be sufficiently lowered to permit the valve plate 14 to move to its closed position by gravity and open communication between the chamber 8 and the pipe 12. The pressure in said chamber now forces the water through the pipe 12 and into another ot' the chambers 8, the Water impinging in its passage upon the check valve plate 19 and closing communication between the pipes 12 and 17. Upon a further decrease in pressure caused by the discharge of water into the last named chamber, the check valve in the end of the pipe 12 seats itself against the pressure of the water. The valve 19 now opens so that the Water is discharged through the pipe 17 into the last ot the chambers 8b until the pressure of steam or gas upon the water decreases to such extent that the same is not capable of opening the check valve in the end of the pipe 17 Thus it will be seen that the pressure in each of the chambers of the tank or reservoir differs, the pressure in the iirst named chamber in which the valve 11 is located being the greatest and the pressures in the chambers into which the pipes 16, 12 and 17 extend decreasing in the order named. This disposition of the water admitted to the first chamber is repeated with each rotation of the rotary valve plate 24.

32 indicate discharge pipes which communicate with each of the chambers with the exception of chamber 8 in which the valve 11 is located and into which the water is primarily discharged from the stand pipe 10. rThe pressure ot' water from each of the pipes 32 will be diiferent so that they may be connected to flexible hose and the water conducted to diterent places and used for different purposes. Cocks 33 also communicate with the chambers so that they may be quickly drained and left open to air the chambers.

From the foregoing it will be seen that T have devised a very simple hydraulic power apparatus whereby a number ot ditierent water pressures may be obtained. By means ot my device the necessity 01"' employing pressure cylinders and pistons is entirely eliminated. 1t will be obvious that compressed air may also be used besides steam and gas to secure the desired pressure upon the water contained in the chambers. With each rotation of the valve plate 24 communication is made with the outlet pipe 29 to relieve the chamber ot' pressure and permit water to enter the same from the stand pipe 10. The pipe 21 thus serves as an exhaust and inlet pipe for the chamber. The arrangement of the pipes and check valves to maintain the plate 14 in open position. lVhen the water in each of the chambers is at whereby the water is caused to flow into the several pressure chambers is very simple and at the same time highly eiiicient in practical use. The heat generated within the chamber S into which the pressure fluid is discharged is equally distributed about the walls of the various chambers by means of the body of water in which the storage tank is disposed.

The apparatus is constructed of very few parts thereby minimizing the necessity for repairs and it is extremely durable in construction and may be manufactured at a comparatively low cost.
